The calpain system is ubiquitous in cells, mainly comprising calpains and calpain inhibitors, and is a widespread calcium-dependent cysteine protease in organisms that is involved in many cellular processes such as muscle degradation in vivo and affects the tenderness of meat after animal slaughter. The study found 128 DEGs that probably regulated tenderness traits were selected from 16 significantly enriched GO terms by transcriptome sequencing analysis, and found that the developmental changes in the expression levels of the CAPN1 gene in the pectoral and leg muscles were significantly positively correlated ( P <0.05) with the cumulative growth values of live weight and comb weight. The developmental changes in the expression levels of the CAST gene in the pectoral and leg muscles were not significantly correlated with the cumulative growth values of live weight and comb weight. Our results helped demonstrate the potential molecular mechanisms of tenderness in chickens and provide valuable information for chicken breeding.

目的探讨出生后食管偏离指数对胎儿左侧先天性膈疝(left-congenital diaphragmatic hernia, L-CDH)患儿临床结局的预测价值。方法收集2016年1月至 2023 年2月广州医科大学附属妇女儿童医疗中心收治的103例产前诊断的L-CDH患儿的临床资料进行回顾性分析。根据患儿结局分为存活组(82例)和死亡组(21例), 以及是否需要ECMO支持分为ECMO组(25例)和非ECMO组(78例)。所有患儿均在入院后24 h内行胸腹部X射线检查, 同时计算食管偏离指数和心脏偏离指数。采用独立样本t检验或Fisher精确概率法进行分析组间患儿一般情况及生后影像学特征差异, 采用受试者工作特征(receiver operating characteristic, ROC)曲线评价出生后影像学指标对L-CDH存活及生后ECMO支持的预测价值。结果存活组患儿食管偏离指数及心脏偏离指数均低于死亡组[(10.5±5.3)%与(18.0±4.5)%, t=-5.47;(37.7±7.1)%与(42.8±8.2)%, t=-2.62;P值均<0.05]。ECMO组患儿食管偏离指数及心脏偏离指数均高于非ECMO组[(18.0±4.3)%与(10.1±5.2)%, t=6.34;(42.4±7.9)%与(37.6±7.1)%, t=2.63;P值均<0.05]。ROC曲线分析显示, 食管偏离指数和心脏偏离指数预测需要ECMO支持的曲线下面积分别为0.879(95%CI:0.805~0.953)和0.712(95%CI:0.570~0.854), 界值分别为11.7%和41.7%;预测患儿存活的曲线下面积分别为0.854(95%CI:0.761~0.947)和0.735(95%CI:0.582~0.887), 界值分别为15.8%和41.7%。结论出生后食管偏离指数对胎儿L-CDH需要ECMO支持及存活具有一定的预测价值。
